CARBON NATION - A New Documentary On Climate ChangeBy Scott Zaretsky

I have to admit, I’m a little “documentary filmed–out” these days. The thought of sitting thru and screening a “climate change” film after a day at the “office” wasn’t quite the movie-mojo I had signed up for. That said, I found Award-winning director Peter Byck’s CARBON NATION to be the best film on climate change I have ever seen.

Very early in the shooting of Carbon Nation (www.carbonnationmovie.com) I learned about Green Hawks in or advising the Pentagon – men like Col. Dan Nolan (US Army retired) and former CIA chief Jim Woolsey. Warriors who knew we were fighting in Iraq and Afghanistan for a resource called oil. Resource wars are not new. As Woolsey told me, 200 years ago wars for fought for salt – the key ingredient to keeping food from rotting on long ocean voyages. (Do you know the US policy towards Japan before they bombed Pearl Harbor? We had imposed an oil blockade – preventing oil supplies from reaching their mainland.)

The best way to promote clean energy is to ignore climate change and focus on things like jobs, money and national security

IN THE 1970s everyone thought environmentalism meant granola, which meant health food stores, which meant carob, a horrible substance the health-foodies told us we should eat instead of chocolate. In the same decade, US president Jimmy Carter reduced the speed limit on interstates from 70 miles per hour to 55 mph to save energy. Carter got kicked out and carob made it feel like "doing the right thing" was akin to taking medicine: the environmental movement was saddled with pseudo-chocolate and painfully slow driving.

Now motoring is going electric, not because of its moral compass - it's just that the engines perform much better. I took a ride with Elon Musk behind the wheel of his company's new Tesla Roadster electric sports car. He floored it, and the g-force made my headphones rotate swiftly around my head. Goodbye carob, hello delicious chocolate!

I'm a whiny liberal film-maker who has spent the past four years making Carbon Nation, a documentary about climate change solutions that doesn't even care if you believe in climate change. I know climate change is real and happening, but you don't have to agree with me to see the benefits of clean energy. A low-carbon economy is also a national security issue, a great business opportunity, even just a way to keep families together. As The New York Times writer Thomas Freedman says in the movie: "It's the most patriotic thing you can be, do, think or feel today. Green is the new red, white and blue."

This is exactly where I have found great areas of common ground with knuckle-dragging conservatives. Finding common ground isn't supposed to be possible in the US - our lost, polarised land. But I'm here to tell you we're not polarised, and we're far from lost. We're being told we're polarised to keep political pundits in business. Problem is, that story is being bought by most in Congress, so our march to a clean energy economy has been stymied, to say the least.
